Thumbnail sketches are small, quick drawings that help artists and designers visualize ideas before creating larger, more detailed works. These sketches are typically done in a compact format, allowing for rapid exploration of concepts, compositions, and layouts. They serve as a preliminary step in the creative process, enabling artists to experiment without committing to a final design. In various fields, such as graphic design, illustration, and architecture, thumbnail sketches are essential for brainstorming and refining ideas. They can capture the essence of a project, making it easier to communicate concepts to clients or collaborators. Overall, thumbnail sketches are a valuable tool for creativity and planning.
